“A High Court judge has considered the applications on the papers and adjourned the cases to a hearing in open court.

“The judge has issued interim injunctions preventing their removal prior to those hearings. The judge has directed the hearings be fixed urgently.”

The grounds for the appeal by Abu Hamza and al-Fawwaz were not immediately clear. Their lawyers did not return calls seeking comment.

A British government source told AFP the appeals by the two terror suspects were a “delaying tactic”.

The government would continue working with the police and the US authorities to ensure the extraditions went ahead as quickly as possible, the source said.

Hamza, the hook-handed former imam of the Finsbury Park mosque in north London, is wanted in the United States on charges including setting up an Al-Qaeda-style training camp for militants in the US state of Oregon.

He is currently serving a seven-year jail sentence in Britain for inciting followers to murder non-believers in speeches on the streets of London.
